Capacitance-transient-spectroscopy model for defects with two charge states

Visualizing transient dark states by NMR spectroscopy.

Myriad biological processes proceed through states that defy characterization by conventional atomic-resolution structural biological methods. The invisibility of these 'dark' states can arise from their transient nature, low equilibrium population, large molecular weight, and/or heterogeneity. Although they are invisible, these dark states underlie a range of processes, acting as encounter com...

A charge-based capacitance model of short-channel MOSFETs

channel effects are included in the model. In this model, charge conservation holds and channel charge partitioning are properly treated. The simulation results clearly show the importance of 2-11 field-induced effects to short-channel MOS devices. Comparison of the simulated results with reported experimentally measured data shows that the proposed model is far more reliable than the analytica...

Application of the singular valve decomposition–Prony method for analyzing deep- level transient spectroscopy capacitance transients

Decoherence spectroscopy with individual two-level tunneling defects

Recent progress with microfabricated quantum devices has revealed that an ubiquitous source of noise originates in tunneling material defects that give rise to a sparse bath of parasitic two-level systems (TLSs). For superconducting qubits, TLSs residing on electrode surfaces and in tunnel junctions account for a major part of decoherence and thus pose a serious roadblock to the realization of ...

Accurate Model of Capacitance for MEMS Sensors using Corrugated Diaphragm with Residual Stress

In this paper we present a new model for calculating the capacitance of MEMS sensor with corrugated diaphragm. In this work the effect of residual stress is considered on deflection of diaphragm and capacitance of sensor. First, a new analytical analyzes have been carried out to derive mathematic expressions for central deflection of corrugated diaphragm and its relationship with residual stres...
